WILLSEMI Will Semicon · Operational Amplifier · SOT-23-5L

WS72631E-5 from WILLSEMI Will Semicon, in a SOT-23-5L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Out output Amplifier output; the datasheet gives short-circuit current of 130 mA source and 130 mA sink, and an unlimited output short-circuit duration.
2 -Vs power_in Negative supply rail; the part operates from 2.2 V to 5.5 V single-supply or ±1.1 V to ±2.75 V split-supply, with a 6 V maximum supply voltage (V+ minus V-).
3 +In input Non-inverting input; the input common-mode range is (V-)-0.1 V to (V+)+0.1 V typical, and (V-)-0.2 V to (V+)+0.2 V absolute maximum.
4 -In input Inverting input; the input common-mode range is (V-)-0.1 V to (V+)+0.1 V typical, and (V-)-0.2 V to (V+)+0.2 V absolute maximum.
5 +Vs power_in Positive supply rail; the part operates from 2.2 V to 5.5 V, with a 6 V absolute maximum supply voltage (V+ minus V-).
